ERNEST B. SELLEW, OF PAWT UCKET, RHODE ISLAND.

SHAPING-MACHINE.

Application filed May 27, 1912.

To all whom it may concern Be it known that I, ERNEST B. SELLEW, acitizen of the United States, residing at 51 Allen avenue, Pawtucket, inthe county of Providence and State of Rhode Island, have inventedcertain new and useful Improvements in Shaping-llachines, of which thefollowing is a specification.

This invention has reference to an improv ment in the class ofmetal-working machines in which the cutting tool reciprocates over thework in order to plane or shape it into form when it is held in a fixedposition upon the table or work-holder, and particularly to thecylindrical type of table shown on the class of machines patented May 8,1900, No. 64917 5.

The object of this invention is to give to the table on a machine of theclass described, a rigid support to resist the pressure of the tool orcutter brought upon the work by the cutting action, and therefore securegreater accuracy, as well as greater speed in doing the work.

The invention consists principally in the convenient construction of thetable support, whereby the vertical adjustment to the table can be veryquickly and easily made to accommodate that work and then be securelyclamped so that the table may receive an efficient outboard supportduring its entire transverse feeding travel underneath the reciprocatingtool.

The particular application of the outboard support is snown by thedrawing as applied to a table or work-holder of a shaping machine inwhich Figure 1 is a side elevation of the front part only as the back ofthe machine which is not shown, is not a part of this invention and neednot be described. The work holder portion of the machine is shown insection the same being taken at A on Fig. 3 which view is a front endelevation of the machine showing the work holder supported on a hearingwhich can be clamped in position after its vertical adjustment, saidbearing being always a fixed distance under the top of the table inwhatever vertical position the same may be adjusted. The table is of theswiveled type and has tangential flat sides provided with. clampingslots by which the work may be clamped, as shown in the differentfigures. Figs. 2 and 1 show corresponding views to Figs. 1 and 3respectively of an outboard support, of

different construction however, the sliding bearing being clamped on thebase of the machine which is extendedtoward the front to receive it. InF ig. 2 the table portion only of the machine is shown in section, saidsection being taken at B in Fig. 4t.

Similar marks of reference indicate corresponding parts on all thefigures.

0n the drawing, 10 indicates a plate used for clamping the table at itsouter end, in its position as shown, or, after being swiveled around onits trunnion 11 in any desired angular position. The clampingbolt 12, toaccomplish the binding, draws said plate 10 into the trunnion 11, whichhas a counterbore at its outer end to receive a hub which projects fromand is part of said plate 10. This plate 10 is provided with graduationsas shown to determine the angular adjustment of the table. The lowerportion of plate 10 is projected downward to make a U shaped connection10 to rest upon the bearing of the support arm 13. Said support 13 isvertically adjustable and is clamped to the stationary support 14l, bythe clamping bolt 15 which passes through a slot for it in thestationary support 14;. The stationary support let is bolted to theextension of the machine base 16, which is projected toward the front ofthe machine to receive it.

In Fig. 2 the binder plate 17, which corre sponds to the plate 10 inFig. 1, is somewhat different in form, having a hub or hollow stem 18projecting downward from its lower side, which telescopically receives apost 19, which, after it is in its proper vertical position, can besecurely clamped by the binder bolt 20. The lower end of this post 19rests upon a bearing surface 21 which is part of the extension of themachine base 16 as in the case of the construction of Fig. 1. The binderplate 17 is also clamped by the binder bolt 12 in the same manner as inthe first mentioned construction.

In both forms of construction, it is to be noted that the same principleof adjustment between the support proper and the binder plate obtains.In Figs. 1 and 3 the connection between the binder plate 10 and thestationary support 14: is in two parts, namely the extension 10 and thesupporting arm 13, the latter being connected with the extension 10 andadjustably connected with the support 14, so that in this constructionthe elements 10' and 13 together constitute the eX-.

tension which is adjustably connected to the stationary support 14. Inthe construction shown in Figs. 2 and 4, the extension 18 is projecteddown sufliciently far to attord for the same range of adjustment that isatforded by the employment of the two-part extension shown in Figs. 1and 3.

Two desirable forms of construction of the table support are shown incombination with the swiveling type of table.

Having thus fully described and set forth my improvement, what I claimtherein as new and of my invention, and desire to secure by LettersPatent, is,

1. The combination with a swiveled table, and a binder plate engagingthe outer end of the table and having an extension projecting downwardlybelow the table, of a support connected with said extension, the supportand extension adjustable vertically relative to each other.

2. The combination with a swiveled table having a bore in its outer end,and a binder plate having a hub received in said bore, an extensioncarried by said binder plate and projecting downwardly below the table,and a support connected with the extension and adjustable verticallywith respect thereto.

In testimony whereof I afiix my signature in presence of two witnesses.
